I bought my first 4x4, Jeep TJ - Need advice from the wise

I am new to this forum and finally bought myself a 4x4! 2003 Jeep Wrangler 4.0 Auto 153 000kms. Extremely Excited.
Beore I go jetting off into the dune/ bush I have a few questions, many of which have been addressed previously but
seem to be slightly outdated. Apologies if im in the wrong section or if I should have posted in Newbie's first?

1. When I buy any car, no mater how well looked after, I like to do a complete oil/fluid change. Engine, Diff, transmission, coolant,
power steering etc etc... Can someone recommend an Indie or even a good home mechanic in Cape Town who could assist me? I would like the person to have a good knowledge of Wranglers and give my car a complete once over. If there is anyone in the Southern Suberbs it woul dbe great!
2. How to I go about meeting up with like minded individuals to go offroading with me? Nothing too hectic as I'm a beginner but I wouldn't
mind going with someone patient and willing to recover me if I get stuck!I was thinking Atlantic Dunes is a good start for me.

No its not my daily drive, it's a bit thirsty! Lucky enough to have a Golf 7 as well. It's a 2003 model 153000kms, one owner, not a mark or scratch anywhere inside or underneath. Brand spanking new BF Goodrich Tyres as well. Bought it from an awesome guy off gumtree for R85k.
Bought a recovery kit and compressor today which I'm excited to use.
Just need to find someone to join me on a chilled 4x4 day trip and teach me a thing or two.
